FRIEDRICH SGHREINER, OF PLAINFIELD, NEl/Vv JERSEY.

STEREOTYPE-CASTI NG BOX.

SECIFICATION forming part of Letters Patent No. 773,528, dated October 25, 1904.

Application filed November 25, 1903. Serial No. 182,620. No model.)

To all 7077/0772, it 777mg/ concern:

Be it known that I, FRIEDRICH SGHREINER, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented a new and Improved Stereotype-Casting B0X, of which the following' is afull, clear, and exact description.

Heretofore in stereotype-casting boxes it was only possible to cast plates with cores or legs of column or half-column sizes, and any other sizes of plates between columns or halfcolumns had to be cast as solid type-high plates or as thin plates for mounting on wooden bases or to be used on ce-rtain solid iron blocks.

The object of my invention is to provide a new and improved casting-box constructed in such manner that any size of plates for printing can be cast with cores or legs that will cross each other level and produce type-high plates, so that whether a small or large sized plate is cast it will have level crossing bearings which will resist printing much better than those having lengthwise-running legs or cores, as heretofore formed.

My invention will overcome the springing or sinking of plates while casting, linishing, or printing the same, and it will also avoid trouble to the stereotyper in sawing the plates in column sizes. Heretofore in sawing plates with lengthwise-running cores or legs the stereotypers had to use great care not to saw off too much on one side, so that the other side of the column also had a leg. Further, the stereotypers had to be very careful in placing the matrix in the casting-box so that it would cast the plates with its lengthwise-running cores or legs just beneath the columnrules, so that these lengthwise-running cores or legs would be accurately in the center of said column-rules or in the center between the columns. My invention will overcome all of these difficulties, and plates which are cast with my level crossing' cores or legs may be sawed in any irregular sizes, and also the same can be cast in any suitable or irregular sizes no matter how small or large.

I will describe a stereotype-casting boX embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a front view of a stereotypecasting box embodying' my invention and showing the improved section cope or cover open. Fig. 2 isa cross-section thereof with the box-sections closed. Fig. 3 is a section on the line m w of Fig. 2. Fig. 4 is a plan view of the bottom plate with the several gages assembled thereon. Fig. 5 is a perspective view of a section-gage employed, and Fig. 6 is a perspective view of a matrix-gage.

Referring to the drawings, l designates the bottom plate of a casting-box, and 2 the cope or cover therefor and having' swinging connection with the bottom plate. rlhe inner side of the cope or cover is provided with bosses 3, the side walls of which are tapered, the smaller portions being' at the outer ends. These bosses form walls for lengthwise channels or grooves 4 and transverse channels or grooves 5, the grooves 5 of course crossing the grooves 4, all being on a level plane.

A section-gage 6, which is substantially V- shaped in cross-section, is designed to fit accurately' in any one of the grooves or channels of the cope or cover, and arranged underneath the gage 6 is the matrix-gage 7, which consists of a flat strip of metal and has suiicient width to eXtend substantially from center to center of the opposite. bosses 3. These two gages are to regulate the irregular sizes and the type-high thickness of the cast plates.

Arranged at the inner side of the bottom plate 2 is a head-gage 8, which has a projecting flange 9 suciently high to allow the inserting underneath the same of the end of the gage 6 and the ends of side gages 10. The cope or cover on its under side is provided with a recess ll to receive the plate forming the Jflange 9, whereby when the cope or cover is closed the space will be type-high within the casting-boX-that is, the space between the bottom plate and the cope or cover.

The purpose of the projecting flange 9 on the head-gage is to push loose the plates from the level crossing grooves or channels, as will be hereinafter described.

IOO

It will be seen that the gages employed close the opposite sides of. the casting-box and the inner end and also separate the same between the sides. rl`he opposite endv is open to permit the inliow ot molten metal.

The casting of plates Vfor printingI purposes having irregular sizes with level crossing cores or legs is done as follows: A piece of matrix a ot' any irregular size is placed back down on the lower plate of the casting-box. The head-gage is now to be placed close to the margin called the bolster or ridge of the matrix. Then the side gage on the outer side bolster is to be placed in position. rlhen the matrix-gage is placed on the inner side bolster of the matrix, and upon this the section-gage is placed, so as to lit into one of the longitudinal or lengthwise channels or grooves. Thus the said gage serves as a dam to prevent the molten metal from fiowing out of the inner side ot' the casting-box. The matrix-gage regulates the sizes of the plates, so that the next size of the matrix maybe one-eighthof an inch, three-eighths of an inch wider or smaller, or of any width, and all the attendant has to do is to place the matrixgage on the side holsters of the matrix to cast plates with level crossing legs or cores. As soon as the casting-box is closed it is firmly locked, so that no metal can run out of the crossing grooves or channels. By these crossing grooves or channels much better plates can be cast than by the ordinary method, as there is no chance for sinks, as is often the ease in the old column-cores.

Plates Jformed in accordance with my invention will last much longer in a press on aecount o'f having a better base formed by the level crossing legs or cores. As soon as the metal is Yformed in the casting-box and becomes set or hard the box is to ybe opened, the section-gage pulled out, and the cope or cover raised. By this operation the projecting {iange 9 holds down the casting-plate, so that the plate will easily loosen out of the grooves or channels and while the head-gage remains in position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent4 l. A stereotype-casting box, comprising a bottom plate, a cope or cover having tapered bosses, the said. bosses forming walls of crossed channels, a section-gage for engaging in a channel, a matrix-gage, and a head-gage.

2. In a stereotype-casting box, a bottom plate, a cope or cover having bosses forming walls et' crossed channels or grooves, a section-gage for engaging' in a channel or groove, a matrix-gage on which said section-gage is designed to be placed` a side gage, and a headgage having a projecting liange for engaging over the ends of the iirst-named gages.

3. A casting-box comprising a bottom plate, a cope or cover having tapered bosses forming the walls of crossed channels, a sectiongage corresponding to the cross-section of the channels and adapted to engage in any one of the same, a matrix-gage, a side gage, and a head-gage having a projecting flange for engaging over the end of the side gage and also over the end of the section-gage, the said cope or cover having a recess for receiving the plate forming said flange.

In testimony whereof l have signed my name to this speci lication in the presence of two subscribing witnesses.
